Ligands: bonding nature complexes, 91 defined

The ligand field potential, Vuf, defines the energies of the d-(oi /-) orbitals and is the only part of a conventional LFT calculation which includes the symmetry of the complex. Hence,. lf is the only part of the Hamiltonian which can make general direct contact with M—L bonding. Hpp and Hus may still be relevant but only in terms of the overall, averaged nature of the metal-ligand interaction.
